Final answer:
Class C fires, typically electrical fires, are represented by a blue color and square shape in safety and firefighting codes.
Step-by-step explanation:
In safety codes and fire fighting, various classes of fires are denoted by letters and symbols. The class C fires, often associated with electrical fires, are depicted by a blue color and square shape. It is essential to remember that Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets.
Fires started by electrical equipment often have a high risk of electrical shock if water is used to control the fire, hence a special approach is essential when dealing with such types of fires. Using a CO2 or Dry Chemical Extinguisher is typically recommended for a Class C fire. The blue square symbol is associated with Class C to enable clear and quick identification during an emergency.
